Title: Motor controlling system
Inventor: OHASHI YUJI
IPC: H02P29/00
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To prevent a damage of an AC servo motor by an excessive driving current. SOLUTION: This controlling system 10 includes a microcomputer 14 connected to the driving circuit 12 of an AC motor 11 provided with an encoder 13 and the microcomputer 14 controls the rotation of the motor 11. In this system, the microcomputer 14 is constituted in such a way as to switch over to a closed-loop or open-loop control by letting it switch over to chose whether or not the output of the encoder 13 is fetched as a feedback signal. If transferring action is performed by the motor under the state of the open-loop control, the system prevents overcurrent from flowing in the motor even if catch occurs during a transfer so that damage to the motor, driving circuit or objects being transferred can be prevented. Switching over to the closed-loop control to make the motor perform a positioning operation ensures highly accurate positioning control.

Title: Vibration proofing construction for brushless motor
Inventor: TAKAHASHI OSAMU
IPC: H02K29/00
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To reduce noise, and to enhance the vibration proofing property of a motor against vibration from outside by absorbing vibration of its rotor and stator generated when the motor rotates. SOLUTION: A holding means 16 for holding a rotor and a stator is fixed to the body 19 of a control circuit case with vibration absorbing members 26, 27 having a plurality of ribs 33 in between. The ribs 33 are formed projecting radially to the rotation center of the rotor, and are easy to fall in the directions (a), (b) of forward and reverse rotation of the rotor, and difficult to fall in directions other than those. Since the direction of vibration of the rotor and the stator generated when the motor rotates is the direction of its rotation, the vibration is absorbed by the easiness of falling of the ribs 33 as if the ribs 33 were soft. The ribs 33 become difficult to fall against vibration from outside, as holding-out force is generated in the ribs 33, and the vibration proofing property is enhanced.

Abstract: PURPOSE:To perform the interruption control at a high speed by controlling the interruptions received from the lower rank processors with use of the interruption control masks prepared in a CPU for each lower rank processor and each priority rank as well as the interruption control masks prepared in the lower rank processors for each priority rank respectively. CONSTITUTION:The control masks LM1 and LM2 prepared in a CPU for each priority rank are updated when the interruption control masks set for each priority rank must be updated at a high speed. Then the interruption control masks LM1' and LM2' set in the lower rank processors PU1 and PU2 for each priority rank are updated when the interruption control is desired to each lower rank processor for each priority rank. These masks LM1' and LM2' are updated only when an information processing system is first started or the system constitution is changed. Therefore, the high speed updating operations of the interruption control masks are never affected at all. Thus the high speed interruption control is attained.

Filed: 1993-12-22
Abstract: PURPOSE:To provide a tablet device unified with a display which applies an active matrix drive method to detect coordinates without deteriorating the display quality. CONSTITUTION:The switches 6-11 switch and select the Y and X coordinate signal generating parts 3 and 5 during the detection of coordinates.
